Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Gather safety equipment (gloves, goggles).

2. Inspect and Clean

Tools Required: Brake cleaner, microfiber cloth.
Open the hood and locate the brake fluid reservoir.
Wipe the top of the reservoir with a clean cloth to prevent contamination.
Inspect the reservoir for cracks or damage.

3. Refill Brake Fluid

Tools Required: Funnel.
Using a funnel, add the appropriate brake fluid (DOT 3 or DOT 4, as specified in the owner's manual) to the reservoir until it reaches the "FULL" mark.
Do not overfill; ensure the fluid is at the recommended level.

4. Check for Leaks

Inspect all brake lines, hoses, and connections for any signs of leakage.
If leaks are found, replace damaged components (brake hoses or lines) as necessary.

5. Test the Brake System

Start the vehicle and pump the brake pedal to build pressure.
Ensure the brake pedal feels firm and responsive.
If the pedal remains spongy, further inspection of the brake system may be necessary.
